Digital Output Commands - Stanford Research Systems DS360 Operating Manual And Programming Reference

4-12 Remote Programming
Digital Output Control Commands
Note: The digital output control commands may be selected only when the digital output type is selected.
If these commands are sent when the unit is in analog mode a " N ot Appl " (not applicable)
message will be displayed on the screen and syntax error will occur. The command OUTD1
(digital output) should be sent at the beginning of any program that uses the digital output. Also
be aware that a couple of commands share common mnemonics and values with the normal
analog output (FUNC, STPE, FSTP).
FUNC (?) i
DFRQ (?) x
DAMP (?) x
OUTD (?) i
DIGM (?) i

The FUNC command sets the output function type to i as shown below. The
FUNC? query returns the current function. Note that square, white noise and
pink noise (i=1,2,3) are not valid when the instrument is in digital mode. If the
instrument mode is changed from analog to digital while the function is set to
square, white or pink noise, the function will revert to sine.

0 Sine
4 2 Tone
The DFRQ command sets the digital frequency to x Hertz. The DFRQ? query
returns the current digital output frequency. The frequency is set and returned
with 10mHz resolution. This command doesn't set the frequencies for 2-Tones.
See DTAF and DTBF commands for 2-Tone frequencies.
The DAMP command sets the digital output amplitude to x percent (%). The
DAMP? query will return the digital amplitude in percent. The amplitude is sent
and returned with 0.00001% resolution. This command doesn't set the amplitude
for 2-Tones. See DTAA and DTBA commands for 2-Tone amplitudes.
The OUTD command selects the output mode of the instrument. For i=0 the
output is analog, for i=1 it is digital.The OUTD? query returns the current output
mode.
The DIGM command selects the digital output format of the instrument. For i=0
the format is professional and for i=1 it is consumer.The DIGM? query returns
the current digital output format.
